'This invention relates to methods of and. machines for mak ng shoes, and is herein 11::

lustrated as embodied in a vstapleat'asabeniing- This operation is. commonlyfcarried' out-by means of a stap-le-fastening 1nsert1ng' mainserting machineofthe type disclosed in i United States Letters Patent No.1,059,98 l,. granted April 29,1912, onan application filed in the names of E.-Eric kson and llV. Cosgrove; i

In the manufacture of welt shoes the upper is usually lasted over the edge of theinsole and temporarily secured in lastedposition by tacks driven into the insole preferably in the angle-between the feather of the1insoleand the shoulder against which the welt is sewed.

; Before thewelt-attaching operation some or all of the lasting tacks are removed toprevent theirinter'fering with the'needle of the welt attaching machine. maintain the upper in final lasted position,

it is customary to drive staplesot fine wire through the upper into the rib of the insole permanently to secure the upper tothe insole.-

chine of the type referred'to, the operation being performed separately from andf'usually before thetack-pulling operation.

An object of the present invention is to eliminate in the manufacture of shoes the necessity for performing separatefastening inserting rand tack-pulling;operations prior to attachment of the'rwelt .totheinsole. To

this end, onefeature of the invention resides whichhave previously been inserted into the shoe to holdthe upper in lasted position. As

illustrated, the machine comprises staple-insorting mechanism having assoc ated there with a tack-pulling tool operable concurrently with the staple-inserting mechanism to pull lasting tacks asfastenings are driven intothe shoe, the; operation being such thatthe upper is held in lasted position during the finsertionof the staplesandas the tacks are pulled. By the use of the construction idescribed,

when a shoe is presented to the machine to receive staple fastemngs for permanently se- However, in order to.

the insole, the lasting tacks are removed from the shoe, thus avoiding the necessity for per- [RICHARD WILL AM FARMER, for ivonrnamrtrom'nnetann; AssIeNon T NI D forming'a separate tack-pulling operation. I

in its method aspect the invention resides 5 in-the provision of an improvement in methods of making shoes which consists in inserting staple fastenings in a shoe permanently to securetlie upper to the rib oftheinsole and concurrently removing t acks previously inserted'in the shoe to hold the upper inlasted positionl.

Other obj ects and features of the invention:

will appear fromthe following description and claims when considered in connection with the accompanying drawings, in which.

The staple-forming and inserting mecha nism .comprisesaan"outside former 10 'arranged to slidei'n a guideway 1n the frame 12 ofthe machine head, the outside former carrying atits forward end a tongue 14' which projects in front of the former and engages the upper of a; shoe just before a staple is inserted and is co-operable with an anvil;- hereinafter. described to; press to gether close to the'line of insertion of. the

In order to clamp thework and to clinch the staples in the workafte'i" they are driven, opposite the end of the staple nozzle 48 positioned an anvil 50 which is carried by a slide 52 in a forward extension 53 ofnthe i machine frame 12. Theslide52 is provided at its rear end with an. uprightportion' 54 through which extends a bolt-56 having a '5 forked extension 58 embracinga lever arm 60 upon the rock shaft 62, the arm 60 beingadjustably connected at itsfend remote from the shaft to an extension 64' of; the lever arm 24 by meansfof a link 66. The lengthof the link 66 can be regulatedby adjustment of the nut 67' therebyto regulate the stroke of the The construction and arrangeanvil 50. ment of parts are such that, as the drlver 42 forces a staple throughthe upperand the sewing rib of the insole to secure, them together, the lever 60 operates the anvil 50 to move it toward the end of the staple nozzle 48, thus to clinch theends of the staple after it has been inserted in the work. For a'inore detailed description of the construction and operation of the parts so fardescribed, reference may be had to the aforementioned Letters Patent. j

Closely associated with thefastening-inserting mechanism above. describedis tackpnlling mechanism arranged for operation in conjunction with the fastening-inserting mechanism. best shown in Fig. 2, comprises a bell-crank lever (38 carrying-a substantially horizontal forwardly extending tool 'ZOthe'end of which is comparatively thin and flat. and the for ward edge of which extendsadjacent torand substantially in line with the face of the end of the staple nozzle 48. -The forward edge of the tool'FOhas in it a series of notches 7 2 designed to engage lasting tacks in the work and to pull themflwhenthe lever 68 isoperated. The lever68 is pivoted on the shaft 62 and is oscillated on the shaft by the lever 20, the lever8 being provided with a pin 74 positioned in ,aislot 75 in a link 76 adjustablyconnected to the extension 64 of the le ver arm-240 f level-I20. The pin-,andj-slot connection providesfor lost motion between the lever68 and thejli-nk 76, thus permitting movement in a vertical plane of the tack-pull: ing tool 70 'inaloca'ting it in operat ve posi tion with respect to work-presented to the:

nozzle 48. The frame 12 of the machine car ries a lug 77' provided with aset-screw 78 The tack-pulling mechanism,

for engaging with the lever 68- to limit the forward movement of said leverand consequently to limit the movement of the tack-. pulling tool downwardly. For normally maintaining the tool in engagement with work presented to the nozzle 48, there is provided a spring 80 con'nectedto'a portion of the frame 12, the spring being operable to pull the tool '(Odoivn against the upper of a shoe inoperative position with respect to the nozzle 48. w r a i i i i Sincethet ack-pulling tool 7 O is operatively connected to the lever 20 which operates the staple driver 42, the tool is rocked upon the shaft 62 simultaneously with an operation of the driver 42 so'that' a tack-pulling operation is performed at the same time that a staple is inserted in the work:

In the operation of the machine, a shoe is so presented to the mechanism that the upper of the shoe engages the staple nozzle48 and the tack-pulling tool 70 rcstsupon that por tion of the upper positioned between. the

feather of the insole and the shoulder against which thewelt is sewed, and the shoe is, moved by the operator from left to right (Fig. 2). As the shoe is moved across the'face of the staple nozzle 48, successive staples are driven through the upper and the rib ofthe insole and clinched upon the anvil 50, thus securing the upper and insole together progressively,

the staples being inserted in a lineslightly above the path of movement of the needle in the welt-stitching operation, as shown at 82. Simultaneouslywith the operation of the fas teningsinserting mechanism the tack-pulling tool 70 is'oscillated aboutthe shaft 62-in;a'

counter-clockwise direction and the notched 7 ment of the work due to the thrust'of the tool 70 and the driver 42.- I

The operationof the tack-pulling tool is suchthat the tacks are removed automatical 1y as the shoe is moved across the'face of the staple-driving mechanism, thus permitting the operator to give substantially his entire attention to the location o'fthe work-with re spect to'staple-driv'ing mechanism;
